In this work, the solute-solute interaction which exist in the CO2 + n-dodecane+ 3,7-dimethyl-1-octanol system was investigated. Solubility data were measured for three mixtures containing solventfree n-dodecane fractions of 0.50, 0.75 and 0.85, between 308 K and 348 K and pressures up to 14.9 MPa, with solvent mass fractions ranging from 0.375 to 0.984, using a static synthetic method. The data revealed significant solute-solute interactions, which resulted in the occurrence of co-solvency in the two n-dodecane rich mixtures The phase behavior data of the system was modeled, using the RK-ASPEN model. The modeling results indicated that, with the inclusion of a solute-solute interaction parameter, the fitted model was capable of correlating fairly accurate solubility data, but it can only approx. vapor-liquid-equilibrium data. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Quality Control of 3,7-Dimethyloctan-1-ol).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Quality Control of 3,7-Dimethyloctan-1-ol
